MRI Diagnosis of Ligament Trauma of Knee / 实用放射学杂志

ABSTRACT

Objective To evaluate the value of magnetic resonance imaging(MRI) in diagnosing ligament injury of the knee.Methods MRI manifestations of ligament injury of the knee confirmed by operation or joint-screen examination in 32 cases were retrospectively analyzed. All cases underwent routine MR scanning. The cases with suspicious anterior cruciate ligament injury undenwent oblique saqittal section fast spin echo-T_2 weight (FSE-T_2WI )and the cases with suspicious medical accessory ligament injury underwent coronal section fat suppressed-fast spin echo-T_2 weight(FS-FSE-T_2W).Results 36 ligaments were found having injury in all cases, including 16 anterior cruciare ligaments, 14 posterior cruciate ligaments, 5 medical accessory ligaments and 1 lateral accessory ligament. The ligaments injuries included tear completely and part.Conclusion MRI is the ideal non-invasive method for studying ligament injury of the knee.
